// Details: MI driver base implementation class. This class has been created so
// not have to edit the lldb::SBBroadcaster class code. Functionality
// and attributes need to be common to the LLDB Driver class and the
// MI Driver class (derived from lldb::SBBroadcaster) so they can call
// upon each other for functionality fall through and allow the
// CDriverMgr to manage either (any) driver to be operated on.
// Each driver instance (the CMIDriver, LLDB::Driver) has its own
// LLDB::SBDebugger object.
// Gotchas: None.
